sound template structure:

type - MANDATORY string, either "playonce" or "loop", determines behavior of the sound, it must match the flag of the sound that it uses

frequency - MANDATORY table containing 2 values to roll it's own delay from - 'min' and 'max'
vol - OPTIONAL float describing the volume of the sound (defaults to 0.35, aka 35%)
fadeInSpeed - (LOOP ONLY) OPTIONAL float describing how fast the looped sound will fade in
fadeOutSpeed - (LOOP ONLY) OPTIONAL float describing how fast the looped sound will fade out
meetsRequirements - OPTIONAL function, this is where you can add additional validity checks to limit the playback of the sound
